Chalazion Symptoms & Causes


What is a chalazion?

A chalazion is a persistent inflammation or swelling of the upper or lower eyelid. It usually includes the middle part of the eyelid as well.

What causes a chalazion?

A chalazion is caused by a blockage of one of the glands in the eyelid. Swelling may also occur in other parts of the eye due to a secondary infection.

What are the symptoms of a chalazion?

Each child may experience symptoms differently, but the most common symptoms of a chalazion include:

  • a small bump that can usually be felt in the eyelid
  • a gradual swelling of the eyelid
  • discomfort in the eye or difficulty seeing if the chalazion is large

Swelling associated with a chalazion is not usually painful, but the entire lid may become swollen and painful if the initial chalazion becomes infected.

Because the symptoms of a chalazion may resemble other conditions or medical problems, you should always consult your child's physician for a diagnosis.
